Dwight,

The horn is located under the front of the vehicle, passenger side. Two
electrical leads attach.

More often than not, the problem is not the horn itself, but a corroded
ground connection inside the vehicle.

The culprit ground connection is located at the bottom of the steering
column (you will need to remove the steering column cover, first). This
ground connection is prone to corrode due to it's proximity to the floor,
and water that comes in on your shoes.

Hope this helps.
